blecch 

Blecch is a way of conveying that something is gross or disgusting. People use this word for things that taste icky or look or smell gross, etc. The cs and hs at the end of the world emphasize that it's pronounced guttural at the back of the throat. For more dramatic effect, it can be written BLEACCCHHH!

Blecch, I can't stand the taste of caraway seeds!
